If you use it at ordinary times The boarding bridge It is necessary to pay attention to the problems of chain selection in the process of chain selection. So how can we choose the right chain for the boarding bridge?

The boarding bridge is mainly used to transport goods from different working floors up and down; for the narrow and small space which is difficult to solve, such as three-dimensional garage and underground garage with more than two floors, places where the pit can not be excavated, and the top floor height cannot reach the requirements, the product hydraulic system is equipped with anti falling, upper and lower door interactive interlocking, and operation buttons can be set on each floor and the working table of lifting platform to realize multi-point control


Compared with belt drive and gear drive, the chain drive has no elastic sliding and slipping, and has strong overload capacity; it can work well under low speed and heavy load; it can adapt to harsh environment.

Roller chain is a standard part, which is composed of inner chain plate, outer chain plate, pin shaft, sleeve and roller GB1243.1-83 Chain roller A/B Two series, the marking method of roller chain is: chain number ---- Row number x Number of links, standard number. The bearing capacity of chain drive should be determined according to the main failure modes and the corresponding constraint conditions.

The causes of roller chain damage are as follows:

1. The fatigue failure of the chain, because the load of the chain in motion changes constantly, so the chain works under the variable stress state. After a certain number of cycles, the chain plate will produce fatigue fracture or the roller surface will produce fatigue pitting corrosion and fatigue crack.

2. The load when the equipment is working, the load of the chain lifting and the stress generated are the main objects to be considered in the design. When the equipment is in low speed, heavy load transmission or when the chain is suddenly overloaded, the chain is statically broken, and the bearing capacity is limited by the static tensile strength of the chain elements. Under the condition of good lubrication condition and correct design and installation, the fatigue strength is the main factor determining the chain drive.

Low cost and low failure rate of boarding bridge: due to the use of advanced hydraulic system and good control mode, the failure rate of elevator operation can be minimized. Less power consumption: when the hydraulic elevator goes down, it is driven by the pressure generated by its own weight, which greatly saves energy.

These are some important contents that must not be ignored when choosing the boarding bridge chain. I hope this article can help you.
